A month-long high-tech sweep has netted six people on child pornography charges in five Ocean County townships according to the Ocean County Prosecutor’s Office. The dual agency investigation made its first arrest in mid-May and its fifth arrest Thursday. Authorities withheld news of the arrests until Monday to maximize the number of suspects caught. Those arrested include Christopher Pontrelli of Down Hill Run in Toms River, on May 15; John Rupert Woods of Bennetts Mills Road in Jackson, on May 21; Nicholas Hernandez Jr. of Third Avenue in the Manitou Park section of Berkeley, on May 23; a minor, of Staysail Court in the Bayville section of Berkeley, whose name and age were withheld, on June 11; Jesus Hernandez-Juarez of East Fourth Street in Lakewood, on Thursday; and Chad Zehner of Lakewood Avenue in the Forked River section of Lacey.
